Abstract

This conceptual design was commissioned by ESP with the express intention of creating a viable concept for a Kinetic Energy Storage Device (KESD) in the form of a flywheel system. The intention is to glean energy from the national grid when electricity is very low cost and return it to the national grid when energy is more expensive. As an example; one kWh of energy bought in the early morning when demand is low costs approximately £20. If this could be stored until a high demand period, say early evening, the cost would be approximately £250 per kWh. If several KESD’s could be run there would be potential of making a great deal of money. On a national basis; several thousand KESD’s could reduce the necessity for so many power stations. KESD’s could also store solar power and wind power to be used when demand for power is high.
